I think "the shudders" you're seeing is the one caused by play of the main rotors.

The two blades attach after sliding over the pivot pins on the rotor head.
If there is excessive play side to side (try sliding it side to side), you get an action like that.

One of mine did it.
Solution, add a washer of some type to one (or both) of the pins that the rotors slide over.
Make sure it's not think enough that it causes the blades to bind.
They need to pivot completely freely.

I can not understand (sorry a problem of mine is I do not understand well English) you can show a picture of what I should check.thanks

my wife just complained , Why are the end tables from the patio out in the middle of the backyard. I can't believe that she doesn't realise that it is actually a tall building on which my 911 can land and take off from to transport executives and medical items in emergencies.
being an imaginary heli pilot is not an easy job.

It's only 11:30am here, but that is the funniest thing I've heard all day... And I have a 2 year old son who has very interesting thoughts. Lol

Those that have used or are using a 9116 TX with your v911, does your rudder trim work? Mine doesn't. Aileron does.

You can use the 9116 Tx with the V911? Thats interesting.

I just ordered a 9116 this weekend (with guaranteed delivery: Tuesday Oct 9th ) as a larger alternative to the V911 for flying outside on nice days. I like the micros, but theres something appealing to me about flying a larger bird.

I will have to try this when my new V911 arrives later this week.

I'll let you know my experiences with this as I'm curious to try it out!

Those are decent helis, my advice is to order a tail motor or two in advance, a friend of mine has one of those he goes through a tail motor every month or two, but he has like 12 batteries for it and flies it constantly, it is similar to the v911, when you let off the cyclic it stops to a nice hover. Had to unlearn that little trait when I was learning to fly my 450.

Yes, I use the 9116 tx for my 911. You just have to change the AIL and RUD. For the 9116 it's set for REV. For the 911 you have to change it to NOR.

Be careful the first few times you fly the 9116. Very different flight charactoristics then the 911. It's heavy, underpowered, and handles like a bus. Has decent FFF but you really need to anticipate your next move as it's sluggish to respond. Not a bad bird though. I'm going out to fly it now.

I know people have said they've used the GW Xieda 9958 main motor. My Bravo SX main motor died so I tried a 9958 and it's great. Just wanted to mention, if it hasn't been, that the teeth on the 9958 are a better match in the Delrin main gear than the Bravo SX. Super smooth and quiet, and since you get more lift because it has less teeth it would probably be good for those adding a fuselage.

How many pinion teeth does it have?
How does this equate to lift?
Flight time?
